Summary
A vulnerability in the SSL VPN code of Cisco ASA Software could allow an
authenticated, remote attacker to overwrite arbitrary files present on the
RAMFS file system or inject Lua scripts.
The vulnerability is due to insufficient validation of the code that handles
session information for the SSL VPN when a SharePoint handler is created. A
SharePoint handler is created when a valid SharePoint connection is initiated.
An attacker could exploit this vulnerability by sending crafted HTTP requests
to the affected system. The SSL VPN feature must be configured for the system
to be vulnerable.
An exploit could allow the attacker to overwrite arbitrary files on the RAMFS
cache or inject Lua scripts, causing a denial of service (DoS) condition for
the Clientless SSL VPN portal or causing the system to reload.
This vulnerability was reported to Cisco by Alec Stuart-Muirk.
